Smart Com Radio Transceiver IC

RF600T

Smart Radio Evaluation Kit

The Smart Radio Evaluation Kit provides a hardware platform to enable

fast development of Radio applications.

Supplied as a pair of boards, each can accept a variety of RF Modules

including transmitters, receivers and transceivers, an RS232 port is

incorporated for direct connection to a PC.

The boards may be used for a wide range of tasks from simple RS232

data transmission to integrated system development and is the ideal

platform for exploring the advantages of using the “Smart Comms” range

of ICs and radio modules.

This eliminates the need to construct hand-wired prototype boards, which

are rarely successful in creating a valid environment for the development

of radio systems. (prototyping board also contains large stray capacitance

values which has a detrimental effect on the RF connections).

Achieving Optimum Range

Range is dependant on many factors including

1. RF Power output

2. Receiver sensitivity

3. Antenna efficiency

4. Local environmental conditions and any local Interference

5. Data Type which is being transmitted.

Whilst items 1-4 are dependant on the system hardware design, item ‘5’ is equally important and often

overlooked. Given that there is a legal maximum power output which can be transmitted, and a limit on the

sensitivity of the receiver (usually constrained by cost), and that the antenna can never achieve 0dB loss

(100% efficiency), then the data structure and coding is an important aspect of the design.

The RF600T uses a fully balanced Manchester encoded data protocol designed for optimum use of the

radio transmission path. Manchester encoding enables the receiver ‘data slicer’ to maintain efficiency for

the duration of the data packet, (unlike many other encoder/decoder systems) which results in reduced bit

errors and therefore ensures maximum range.
